Abstract
Electrical devices comprised of nanoscopic wires are described, along with methods of their manufacture and use. The nanoscopic wires can be nanotubes, preferably single-walled carbon nanotubes. They can be arranged in crossbar arrays using chemically patterned surfaces for direction, via chemical vapor deposition. Chemical vapor deposition also can be used to form nanotubes in arrays in the presence of directing electric fields, optionally in combination with self-assembled monolayer patterns. Bistable devices are described.

1-23. (canceled)
A method comprising:
- forming a nanoscopic wire on a surface in a pattern dictated by a chemically patterned surface, wherein the nanoscopic wire is a preformed wire and the chemically patterned surface comprises at least first and second portions which attract the nanoscopic wire and at which wire deposition is desired, the method comprising applying the preformed nanoscopic wire to the surface across the first and second portions.

31-96. (canceled)
A method, comprising:
- depositing two or more nanoscopic wires on a surface in a pattern dictated by a chemically patterned surface,
- wherein the two or more nanoscopic wires are preformed wires and the chemically patterned surface comprises at least first and second distinct portions which attract the wires,
- the method comprising depositing at least one of the nanoscopic wires at the first portion and at least one of the nanoscopic wires at the second portion.
